摘　　要：压电智能结构是目前智能结构的研究热点之一,用途广阔,并取得了丰富的研究成果。文章综述了压电智能结构中的传感器/驱动器及其系统和基于压电传感器的常用监测方法以及在土木工程中的研究和应用等,并对压电智能传感结构工程实用化的前景提出看法。Piezo-structure, which has widely shown promising application, is one of present focusing investigations on intelligent structures. Many significant advances have been made in this field. Some fundamental problems of piezo-intelligent sensor structures, such as sensor, sensor/actuator system, detection methods based on piezoelectric sensor and application in civil engineering are reviewed in detail. The problems, which must be resolved in the process of application of piezo-intelligent sensor structure to practical civil engineering, are put forward.
